New PU Ultra-Thin Super Soft Clothing Fabric

< p > > Description: 1. cooperate with < a href= "http://sjfzxm.com/news/index_c.asp" > textile mill < /a > to develop ultra-thin and super soft, and new base cloth suitable for synthetic leather production.

2. research and develop suitable PU resins and necessary auxiliaries.

3. design and optimize the production formula to ensure soft and full handle while producing ultra-thin products. At the same time, it is necessary to maintain the necessary physical and mechanical properties of garment leather.

4. in the synthetic leather production process, the penetration control of the coating process is very Guan Jian. Too much penetration will cause a stiff hand and too little penetration will cause poor adhesion.

In the production of ultra soft and ultra-thin synthetic leather, this problem is more prominent. With a little penetration, the handle is hard, the penetration is slightly worse and the adhesive force is poor. In order to solve this contradiction, the project group collected large amounts of data through laboratory test and workshop trial, and groped for the rules. Finally, the problem was solved by modifying the formula and adjusting the process parameters.

< p > the biggest difficulty of the project is how to ensure thin, soft and light base. It is not wrinkled, not pulled and not narrowed in the whole production process of about 400m, but also ensures that there is a suitable penetration point when gluing.

To this end, the project team first carried out the necessary updating and pformation of the machinery and equipment according to the specific requirements, so that it could adapt to the smoothness of the light and thin base cloth.

In addition, the production of ultra-thin products on the coating table coating accuracy requirements are higher. After the adjustment of machinery and equipment, a large number of experiments were carried out on the new machine platform. Finally, a complete set of ultra thin synthetic leather wet BASE production technology, including printing technology, roller coating process and embossing technology, was finally determined, and the embossing process is the most difficult one.

< p > Project Innovation: Previous wet synthetic leather is generally over 0.6mm. The thin wet synthetic leather fabric developed by the project group is the first step to achieve 0.4mm. The project group has developed ultra soft and ultra-thin wet PU synthetic leather with a thickness of only 0.28mm. The product has the characteristics of light, thin and soft, but also has a rich feel like leather.
